Anita Lobel's eerily topical Potatoes, Potatoes, originally published in 1967, centers on a mother living in a valley between two warring nations, who walls in her home to protect her two sons, and who grows potatoes. When her sons leave as young men, to join the opposing armies, she ultimately brings about peace, as the soldiers shout, ""Hurrah for potatoes and hurrah for mothers!"" (Mar.)
